Regional coupled modeling is one of the frontiers of regional climate modeling,but intercomparison has not been well *** this study,a community regional climate model,WRF4,with a resolution of 15 km,was coupled with a high-resolution(0.1°)North Pacific Ocean model(LICOM_np).The performance of the regional coupled model,WRF4_LICOM,was compared to that of another regional coupled model,RegCM4_LICOM,which was a coupling of version 4 of the Regional Climate Model(RegCM4)with LICOM_*** analysis focused on the 2005 western North Pacific summer monsoon *** results showed that the regional coupled models with either RegCM4 or WRF4 as their atmospheric model component simulated the broad features over the WNP reasonably *** intercomparison of the regional coupled simulations exhibited different biases for different climate ***4_LICOM exhibited smaller biases in its simulation of the averaged June–July–August SST and rainfall,while WRF4_LICOM better captured the tropical cyclone(TC)intensity,the percentage contributions of rainfall induced by TCs to the total rainfall,and the diurnal cycle of rainfall and stratiform percentages,especially over land *** different behaviors in rainfall simulated by the two models were partly ascribed to the behaviors in the simulated western North Pacific subtropical high(WNPSH).The stronger(weaker)WNPSH in WRF4_LICOM(RegCM4_LICOM)was driven by overestimated(underestimated)diabatic heating,which peaked at approximately 450 hPa over the region around the Philippines in association with different condensation–radiation *** of WRF4 with LIOCM is a crucial step towards the development of the next generation of regional earth system models at the Chinese Academy of Sciences.

The aim of this study was to compare the efficiency of four final irrigation protocols in smear layer removal and bacterial inhibition in root canal *** roots inoculated with Enterococcus faecalis were prepared with ProTaper Universal *** teeth were disinfected by conventional needle irrigation,sonic agitation using the EndoActivator device,passive ultrasonic irrigation,or an M3 Max *** with no root canal preparation served as blank controls for the establishment of the infection *** with preparation but no final irrigation served as a post-instrumentation *** the final irrigation,the teeth were sectioned in *** half of each tooth was examined by scanning electron microscopy(SEM)to assess smear layer removal using a five-point *** other half was examined by confocal laser scanning microscopy(CLSM)using the LIVE/DEAD BackLight bacterial viability kit to evaluate the depth of bacterial survival in dentinal *** analysis revealed no significant difference in smear layer removal throughout the whole canal among the EA,PUI,and M3 Max groups(P>0.05).CLSM revealed that PUI achieved the greatest bacterial inhibition depth in the coronal((174.27±31.63)μm),middle((160.94±37.77)μm),and apical((119.53±28.49)μm)thirds of the canal(all P<0.05 *** groups).According to this comprehensive SEM and CLSM evaluation,PUI appears to have the best infection control ability in root canal systems.

刘勰在《文心雕龙·史传》篇提出“实录无隐”“按实而书”的撰史要求,强调史传叙事的真实性原则。同时,受儒学正统尊经思想的影响,中国传统哲学家与文论批评家认为“真”与“善”同构,“求真”是以“求善”为内核的伦理道德行为。刘勰提出“依经树则”“尊贤隐讳”等撰史要求,在“求真”与“意志”之间构成了历史真实与伦理真实的矛盾冲突。这一矛盾既源于刘勰对历史传记“彰善瘅恶”作用的认识,也与魏晋南北朝的社会意识形态和权势阶层休戚相关。“求真”与“求善”的矛盾并非不可调和的二元对立,在两者的张力之间寻求合理的历史叙事空间,是我们立足当前理论语境的努力方向。

冻结法因具有施工方便、强度高、防水效果好及对土体扰动小等优点在软土地区地铁联络通道施工中获得广泛应用。冻结壁平均温度作为衡量冻结效果的重要参数之一,其解析公式求解较为复杂,在实际工程中难以应用。建立了包括冻结管断裂灾害、隧道收敛变形灾害、冻结帷幕收敛变形灾害、冻结帷幕透水灾害和融沉灾害的地铁联络通道冻结壁冻融灾害链式效应机制,并考虑多种布管方案,采用冻结壁平均温度等效梯形法建立完整数据集,利用神经网络的高度非线性特征,建立能同时预测单排、双排和多排(n>3)布管形式下冻结壁平均温度的神经网络预测模型。研究结果表明,基于完整数据集构建的冻结壁平均温度神经网络预测模型能有效地反映不同冻结管布置参数和冻结壁厚度等参数与冻结壁平均温度之间的关系;冻结壁平均温度均随冻结管排数和冻结壁厚度增大而逐渐降低,随盐水温度、冻结管间距和排距增大而逐渐升高。
